Who are you now?

Nick is not in the audience for Fanny's opening night,
and she's worried, but when he makes a late appearance
at the party, she's angry at him until he tells her that a
hurricane has destroyed their casino and he's lost all
her money. Fanny doesn't think it's that big a deal, and
this makes Nick angry. Fanny doesn't understand why:

Who are you now,
Now that you're mine?
Are you something more
Than you were before?
Are you warmer in the rain,
Are you stronger for my touch,
Am I giving too little
By my lovin' you too much?
How is the view,
Sunny and green?
How do you compare it to
The views you've seen?
I know I am better, braver and surer too,
But you--are you now--
Who are you now?
Are you someone better for my love?
